Course Description:
Introduction to Drawing Instruments, Equipment and Materials including their Descriptions,
Uses and Cares. Points, Lines and Planes. Definition of Points, Line Types, Uses, Dimensioning
types, Letterings, Common Errors.
Plane Geometry:
• Lines (Bisection, Perpendiculars, Equal and Proportional divisions)
• Angles (Different types, bisections and basic construction)
• Triangles (Different types and various Constructions given different data)
• Circles (The Parts, Inscribing/Escribing, and Internal and External Tangents)
• Quadrilaterals (Types, Constructions given different data)
• Polygons (Types, Constructions, and General construction methods)
• Ellipses (Construction using different methods)
• Scales (Construction of Plain and Diagonal scales)
Basic Principles of Orthographic Projection: (Conversion of Pictorial to Orthography), First and
Third Angle Projections, Exercises
Course Objectives:
The objectives of this course are to:
● equip the student in the correct use of drawing instruments, equipment and
materials
● empower student on how to construct basic angles and plane geometry
● equip the student with the basic skill to describe fairly and accurately an object with the
use of different lines, planes and solid/ hollow objects
● enable student to convert three-dimensional drawings to two-dimensional
drawings
and arrange in standard projections.
Method of Teaching/ Teaching Aids:
The method of teaching is participatory as the course is for skill acquisition and empowerment.
Students are encouraged to draw/ work as the teacher demonstrates. The drawing produced in the
studio with the teacher’s instruction constitutes the student’s note.
